Solche zusammengeschalteten Nebenstellenanlagen, von denen in mindestens einer eine Teamfunktion realisiert ist, sind u.a. in Form der von der Siemens AG kommerziell vertriebenen Nebenstellenanlage HICOM 300 bekannt. Eine bekannte Teamfunkti- on ist beispielsweise die Funktion "Anrufubernahme", bei der kommende Rufe innerhalb einer Anrufubernahmegruppe aus mehreren Endgeraten angezeigt werden und an jedem Endgerat, das zur Anrufubernahmegruppe gehört, entgegengenommen werden kann. Eine andere bekannte Teamfunktion ist die Funktion "Sammelanschluß", der unter einer speziellen Sammelnummer erreichbar ist. Hierbei kann jeder Teilnehmer eines Sammelanschlusses auch unmittelbar über eine individuelle Rufnummer angerufen werden, über die spezielle Sammelnummer werden jedoch alle Teilnehmer erreicht. Die Sammelnummer ist bei- spielsweise einem Master-Endgerat zugeordnet. Eine weitere bekannte Teamfunktion ist die integrierte Vorzimmeranlage, die auch Chef-Sekretar-Anlage genannt wird.Such interconnected private branch exchanges, of which at least one has a team function, are known, inter alia, in the form of the private branch exchange HICOM 300, which is sold commercially by Siemens AG. A well-known team function is, for example, the "call pickup" function, in which incoming calls within a call pickup group from several end devices are displayed and can be answered on each end device that belongs to the call pickup group. Another well-known team function is the "hunt group" function, which can be reached under a special hunt group number. Each participant in a hunt group can also be called directly via an individual number, but all participants can be reached via the special hunt group number. The group number is assigned to a master terminal, for example. Another well-known team function is the integrated hall system, which is also called the executive secretary system.
Bei bekannten KommunikationsSystemen sind alle Teilnehmer ei- nes Teams an eine einzige Nebenstellenanlage angeschlossen und werden über dieselbe Netzanschlußeinrichtung an ein übergeordnetes Kommunikationsnetz vermittelt.In known communication systems, all participants in a team are connected to a single private branch exchange and are switched to a higher-level communication network via the same network connection device.
Aufgabe der Erfindung ist es, ein Kommunikationssystem be- reitzustellen, bei dem eine Teamfunktion auch mit abgesetzten Teamteilnehmern realisierbar ist.The object of the invention is to provide a communication system in which a team function can also be implemented with remote team participants.
Diese Aufgabe lost die Erfindung durch ein Kommunikationssystem m t den Merkmalen des Anspruches 1.The invention achieves this object by means of a communication system with the features of claim 1.
Erfindungsgemaß ist vorgesehen, daß mindestens ein erstes Teamendgerat des Teams unmittelbar über eine Teilnehmeranschlußeinrichtung an einen Vermittlungsknoten der ersten Nebenstellenanlage angeschlossen ist und mindestens ein zweites Teamendgerat als abgesetzter Teilnehmer des Teams über eine Teilnehmeranschlußeinheit an einen Vermittlungsknoten der zweiten Nebenstellenanlage als Endgerat angeschlossen ist, wobei dieser abgesetzte Teilnehmer über den Vermittlungsknoten der ersten Nebenstellenanlage, eine Hotline-Verbindung zwischen der ersten und der zweiten Nebenstellenanlage und einen Vermittlungsknoten der zweiten Nebenstellenanlage erreichbar ist.According to the invention, it is provided that at least one first team terminal of the team is connected directly to a switching node of the first private branch exchange via a subscriber line device, and at least one second team terminal device as a remote subscriber of the team is connected via a subscriber line unit to a switching node of the second private branch exchange as a terminal unit, the latter being remote Participants can be reached via the switching node of the first private branch exchange, a hotline connection between the first and the second private branch exchange and a switching node of the second private branch exchange.
Eine in der ersten Nebenstellenanlage vorgesehene Teamfunkti- onsSteuerung bewirkt für kommende Rufe eine automatische Anrufumleitung zu Team-Ersatzteilnehmerendgeräten, wenn sie erkennt, daß die Hotline-Verbindung zur zweiten Nebenstellenanlage und somit zu den abgesetzten Teamendgeräten gestört ist.A team function control provided in the first private branch exchange automatically calls for incoming calls to team replacement subscriber terminals when it detects that the hotline connection to the second private branch exchange and thus to the remote team terminals is faulty.
Der Anschluß von Teamendgeräten als abgesetzte Teilnehmer über eine Hotline-Verbindung ermöglicht es, Teilnehmer eines Teams innerhalb eines Firmennetzes in beliebigem raumlichem Abstand zueinander anzuordnen.The connection of team terminals as remote participants via a hotline connection enables participants to Arrange teams within a company network at any spatial distance from one another.
Eine automatische AnrufUmleitung zu Team- Ersatzteilnehmerendgeraten bei gestörter Hotline-Verbindung zur zweiten Nebenstellenanlage stellt insbesondere in dem Fall, daß ein beträchtlicher Anteil der Teamendgerate abgesetzte, über die Hotline zu erreichende Endgerate stellt sicher, daß die verbleibenden Teamteilnehmer bei Ausfall der Hotline und somit Reduzierung des Teams um die Teamteilnehmer der abgesetzten Endgerate nicht überlastet werden bzw. die erforderliche Dienstleistung immer noch ohne zu große Verzögerung geleistet werden kann.An automatic call diversion to team replacement subscriber terminals in the event of a faulty hotline connection to the second private branch exchange ensures, in particular in the event that a significant proportion of the team terminals are sold and the terminals can be reached via the hotline, ensure that the remaining team participants in the event of a hotline failure and thus a reduction in Teams around the team participants of the remote devices are not overloaded or the required service can still be provided without too much delay.
Eine besonders gunstige Ausgestaltungsform eines erfindungs- gemaßen Kommunikationssystems sieht vor, daß die Teamfunktionssteuerung die Verfügbarkeit der Hotline-Verbindung zwischen den beiden Nebenstellenanlagen durch Prüfung der für die transparente Übertragung der Teilnehmer-zu-Teilnehmer- Meldungen für die abgesetzten Teilnehmer erforderlichen Si- gnalisierungsverbmdung erfaßt. In diesem Fall benotigt die Verfugbarkeitsprufung keine B-Kanal-Ressourcen. Außerdem ist keine zusatzliche Signalisierung erforderlich.A particularly favorable embodiment of a communication system according to the invention provides that the team function control detects the availability of the hotline connection between the two private branch exchanges by checking the signaling connection required for the transparent transmission of the subscriber-to-subscriber messages for the remote subscribers. In this case, the availability check does not require any B-channel resources. In addition, no additional signaling is required.
